【摘要】 目的:比较双J管不同留置时间对输尿管软镜碎石术后排石效果及并发症发生率的影响。方法:采用前瞻性研究方法,依据纳入标准,按照术后双J留置时间,将输尿管软镜碎石术后留置双J管140例患者,随机分为1周拔管组及4周拔管组,每组70例。比较分析两组手术后清石率、并发症发生率。P<0.05为差异有统计学意义。结果:1周拔管组和4周拔管组结石大小分别为(1.6±0.3)和(1.5±0.4)cm(P>0.05),4周拔管组尿路感染、膀胱刺激并发症发生率高于1周拔管组,差异有统计学意义(P<0.05),两组间腰痛、血尿、并发症发生率等方面差异无统计学意义(P>0.05),术后1个月总清石率分别为88.6%(62/70)和94.2%(66/70),差异无统计学意义(P>0.05)。结论:输尿管软镜联合钬激光碎石术后双J管留置1周安全有效,在减少并发症发生的同时不影响残石清除率。更多还原

【Abstract】 Objective:To compare the effect of different double J tube indwelling durations on ureteral lithotripsy after flexible ureteroscopic lithotripsy and the incidence of complications.Methods:According to the inclusion criteria and the time of extubation,aprospective study was conducted on 140 patients who were randomly divided into one-week extubation group and four-week extubation group,70 cases in each group.The stone clearance rate and the incidence of complications were compared and analyzed between the two groups.Probability(P)value of less than 0.05 was taken to indicate statistical significance.Results:The stone size in one-week extubation group and four-week extubation group was(1.6±0.3)and(1.5±0.4)cm(P>0.05),respectively.The incidence of urinary tract infection and bladder irritation complication in four-week extubation group was significantly higher than that in one-week extubation group(P<0.05).There was no significant difference in the incidence of low back pain and hematuria between the two groups(P>0.05).After 1 month,the total stone clearance rates in one-week extubation group and four-week extubation group were 88.6%(62/70)and 94.2%(66/70)(P>0.05).Conclusions:One-week indwelling time after flexible ureteroscopy combined with holmium laser lithotripsy indwelling double J tube is safe and effective,which reduces the incidence of complications without affecting the residual stone clearance rate.更多还原
